The invention discloses a multi-mode hybrid power driving system and a control method.The multi-mode hybrid power driving system is characterized in that an engine is in transmission connection with a first transmission end of a planetary gear train assembly, the engine can drive the first transmission end to unidirectionally rotate around the central axis of the engine, and a first motor is fixedly connected with a second transmission end of the planetary gear train assembly; the output end of the planetary gear train assembly can be connected with or separated from a first wheel set of the vehicle body, and the output end of the planetary gear train assembly can be connected with or separated from a vehicle frame of the vehicle body. The second motor can be connected with or separated from a second wheel set of the vehicle body. The first wheel set and the second wheel set are distributed in the length direction of the vehicle body at intervals. The power battery can be selectively and electrically connected with the first motor and the second motor, and the first motor can be selectively and electrically connected with the second motor. The speed and torque of the engine can be adjusted in a full-speed range, the driving efficiency is high, magnetic loss caused by idling of the first motor and the second motor can be avoided, the structure is simple, and energy consumption is reduced.
